Abstract
An image display including a touch-sensitive display, that creates tactile sensation and movement of an object (3-2) along its surface is provided. Actuators including conductive rods (4-111, 4-112) attached together may be used, such that each rod of the actuator (4-11) may increase or decrease in size when current is applied to that rod to cause the actuator to bend toward a specified direction. Also, an image display that includes ball bearings (1-10) whose rotation is controlled by driving magnets (1-21, 1-22) to cause an object to move is provided. Further, air holes (3-11) tilted in various directions to control object movement by air pressure may be provided. Moreover, rods (3-10) may be moved up or down as activated by driving magnets (2-20). The actuators, rods, ball bearing assemblies, or holes may provide touch sensitivity for the image display.
